Black screen after X loads => Karmic 9.10

[phr33r34lmz]

Hello, forum. I've recently installed 9.10 onto my PC, dualbooting it with XP, and didn't have any problems until I installed the drivers for my Nvidia cards. After installing the drivers and rebooting, X would not start and I would get a terminal-esque screen prompting me to log on. No GUI. After searching online I discovered that, since I have two video cards, Ubuntu didn't know which device and screen to select to output video, so I quickly set up the xorg.conf file to select the proper card and screen. I even added my monitor with the refresh rates and resolutions, and set the card to display it to that specific monitor. Now, instead of going to the terminal after a reboot, I get a black screen and can here the ubuntu drums asking me to log on. So, X loaded but no video on my monitor. Help please!

AMD 64X2 at 6000+
2GB DDR2 RAM at 667
2 GeForce 8600 GTS video cards
Gigabyte GA-M55SLI-s4 motherboard

Here is the xorg.conf file, if any help.

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0

I have this problem too.
I added a line to the device section: Option SLI=On. with the
sudo nvidia-xconfig --sli=on command, but nothing is changed.

I have AMD 4450+, asus m2n4-SLI board and two 8600GT

(sorry for my english :D)
